Hi -
I had forgotten how I became interested in erotic hypnosis until I re-found the story that sold me.
But first, let me say that my interest in forced feminization was instigated by one of the Sandy Thomas publications, whose name escapes me (and can't be found on the site, http://www.lulu.com/spotlight/sandythomas. The story was about a weak guy who takes a job with a lingerie company, and is then bossed into modelling their new bras, the first step in increasingly strict shoves into being fully feminized.
This was a new area for me, and very exciting. I read many Sandy Thomas stories after that, and eventually found "Pretty Sissy Dani", where a jerky guy is hypnotized into being feminized, to his conscious horror, while being incapable of shaking off the hypnotic spell. I read that story many, many times. And now, you can too, at http://entransed.blogspot.com/2007/07/pretty-sissy-dani-chapter-one.html If you like the story, the other chapters are posted in the blog elsewhere.
It took a few years before I found all the fem hypnosis websites, but Dani was my kickstarter. What was yours?
